Resolve downstream Nuxeo Package versions from the requested resolved versions

See AICORE-376 with reproduction case.

• Package A v1 depends on B v1+ (at least)
  • Package A v2-SNAPSHOT depends on B v2-SNAPSHOT
  • mp-install A resolves B v2-SNAPSHOT
• Package A v1 depends on B v1 (strictly)
  • Package B v2-SNAPSHOT also exists
  • mp-install A still resolves B v2-SNAPSHOT
  • mp-install A v1 resolves B v1

In all cases, the --snapshot option is not activated and the distribution is 10.10.

Note that mp-show A will show A v2-SNAPSHOT (is it related or wanted?).
